Topics I've Started

I've solved inverse kinematics for a hand. What I need is to solve it for a hammer. I have an equation that describes where the wrist should go and the orientation of that wrist.
Now, my problem is, how do I translate the point I'm solving for from the wrist to the hammer. This is fairly easy with no rotation in the wrist, it's simply a translation of (0, -8.0f, -16.0f)
My problem is, how do I translate the point if the wrist needs to be rotated to reach the point? If I have
1. the orientation of the point I'm calculating
2. the translation of the point I'm calculating
3. and the translation from the wrist.
How do I solve for the hammer rather than the wrist?
I can solve for the wrist by simply multiplying [1] and [2] together, but I'm completely lost on the hammer.

I realize I'm stepping on a lot of toes asking this questions, but..
I've been playing a MMORPG featuring nProtect GameGuard. Like most MMORPGs, it doesn't support a gamepad, so I've been using the Gravis Xperience to translate my gamepad into key presses. Xperience can't find the MMORPG's process, but when I set it to "all other games", it has no problem emulating the keyboard.
Here's my problem, XPerience is a process hog. It noticeably slows down my computer, and I'm on a decent system. I'd love to write something more lightweight, but I'm having a problem trying to figure out how to get around GameGuard.
GameGuard prevents DLL injection. So, DirectInput Hooking doesn't work, on any process. SendInput doesn't seem to work. Can't find a hWnd to use SendMessage(). It prevents Spy++ from loading. Botters use Process Guard, win9x emulation or a series of other undesirable hacks that I don't wish to use.
I just want a lightweight process to emulate a keyboard or a heavier process that I can turn on and off. Do you guys have any suggestions on how I can accomplish this?
You can always PM me if you don't feel like making the information public.

It's 6:30pm here, so I accidently missed an important news broadcast that I should have taped for someone.
What are my options for getting a tape of it? Is there any service / place I can get a rebroadcast of it AFTER the fact.

I was sure that there would be a draft by now. So sure, I bet money top shelf rum on it. Mushu, you should be very jelous of The Frugal Gourmet, for he has won our bet and therefore won a nice bottle of Myer's Dark Rum, whenever I get around to shipping it out.(Which I promise to get around to by Janurary 5th or so)
So now, as I live in loser land, waiting for The Frugal Gourmet to PM me with contact info, in hopes that 2006 will land me in winner land, I ask you, gamedev, what are you 2005 regrets?

I was reading a quick article on Original IP vs. Licensed IP games. The author stated that he remembers clearly some original IP games like Mario, Sonic and the like, but has no groundbreaking gameplay or awe inspiring memories of any game based on Licensed IP.
I remember quite a few awe inspiring games based on licensed IP, do you remember any?
I'll start.
Batman for NES, I love the cut scenes. I remember resetting the game over and over again to watch them.
Platoon for NES, I love the proto-FPS mazes in that game, which I believe is the second and fourth level. You'd walk down a corridor maze until an enemy appeared and you had only a few seconds to find, aim and fire before you lost your life.
EDIT: For clarity, I think my brain stopped working after noon today.
